Whitlash-Aden Border Crossing

The Whitlash-Aden Border Crossing connects the town of Whitlash, Montana with Aden, Alberta on the Canada–United States border. It is reached by Montana Secondary Highway 409 on the American side and Alberta Highway 880 on the Canadian side. The Whitlash Port of Entry is the least trafficked of all the land border crossings entering the United States, averaging just 2 vehicles per day. In spite of this fact, both the US and Canada spent considerable funds replacing their border inspection facilities in 2012.

The crossing was established in 1929, when Canada decided to close its facility at nearby Pinhorn, Alberta. Prior to the 2012 reconstruction of the US and Canada border stations, the US operated out of a red wooden structure built in 1974, and Canada had a white steel building constructed in 1973 that lacked an inspection canopy. This is one of the few crossings on the Canada–United States border that is located on an unpaved road, although about 100 yards of road surface directly in front of the new US border station was paved in 2012.
